摘要(Abstract):

介绍了在贵阳人民广场的扩建中 ,采用定向爆破拆除以原工人文化宫为中心的旧建筑物的设计及施工过程。通过对诸多因素进行分析与计算 ,决定对该建筑群采用一次爆破拆除 ,在起爆顺序及网络联接中 ,采用交叉复式非电导爆系统组成的微差起爆网络。爆破结果表明 ,本次在复杂环境下拆除旧建筑群的爆破设计及各项安全防护措施是合理可行的
In this paper, the design and process of demolition blasting of a group of old buildings centered around the Worker′s Cultural Palace in the People′s Square of Guiyang are introduced. Based on comprehensive analysis on many main factors and calculation during designing, it was determined that the once through blasting was used for demolition of the building group. For ignition pattern, a short delay detonating network consisted of cross and double nonelectric ignition system was adopted. Blasting results have showed that the blasting design and various safeguards for the demolition of the building group in the complicated environment were reasonable and feasible.
